Book excerpt: The .22 Long Rifle caliber is the most popular ammunition and firearm chambering in the world. It's a backyard plinker, small-game hunter, tactical trainer and Olympic medalist. Along with its .17-caliber cousins, the humble .22 LR is undergoing a massive resurgence in the United States, and around the world, especially in places like the United Kingdom and New Zealand, which effectively ban centerfire chamberings. The rimfire rifle, an historic centerpiece of the shooting community, is trending in a big way, and this book brings the topic into current times. Every major gun manufacturer has brought at least one new rimfire rifle to the market in the last two years, and these models are covered in detail. A sampling of topics included in this full-color work: complete coverage of semi-autos and how they work; the magic of bolt-action accuracy; advice on sharpening up shooting accuracy; match shooting and how to succeed; DIY precision gunsmithing; hunting with rimfires; and the future of the rimfire market. And, to guarantee this work provides complete rimfire coverage, the author also goes deep into the capabilities of the "Might Mice," the .17s: 17HM2, 17HMR and 17WSM.
